When parents pack lunch for their preschoolers, they must take care to check if the perishable foods in the lunches were stored at safe temperatures. If the food was not stored at safe temperatures, it can lead to food-borne illnesses.
Meats, dairy products and vegetables are linked to an increased risk of causing food-borne illness if they are stored at unsafe temperatures.
Researchers found that 99% of the dairy products and 98.5 % of vegetables were stored at unsafe temperatures. 97.4% of the meats were stored at unsafe temperatures.
If perishable foods are left outside for more than two hours they become risky for consumption.
